J-integral is the main effective and commonly used
tool for elastic-plastic cracked material resistance
assessment. Considering ductile behavior of bridges
steel integral approach is suitable for fracture
toughness evaluation. The paper presents the method
of dynamic fracture parameter J-integral evaluation
in case of elastic-plastic deformation of bridge
structural steel. This experimental technique is
based on determination of impact fracture energies
and displacements which correspond to these energies
at the moment when loading rate reaches max and
fracture loads. Theoretical solutions were confirmed
by experimental data obtained from Three-Point Bend
tests of rectangular cross section specimens with V
form notch. Impact loading was generated by impact
tester with drop weight. 5 series of specimens with
different geometry were tested during experiment.
The developed methodology enables to predict the
impact fracture toughness of bridge structural
elements. |
